The news release Bio-inspired: How lobsters can help make stronger 3D printed concrete [1] from RMIT University (with 1 minute video) and the paper Influences of Printing Pattern on Mechanical Performance of Three-Dimensional-Printed Fiber-Reinforced Concrete [2]:

> Underperformed interfacial bond and anisotropic properties are often observed in three-dimensional-printed concrete, where the printing pattern is unidirectional. Such issues could be potentially alleviated by replicating microstructures of natural materials or applying different architectures, where printed layers are arranged into unique and unconventional patterns.

> The addition of steel fibers leads to noticeable improvement on both compressive and flexural strengths of samples in any pattern compared with their counterparts without fibers. Besides, the inclusion of steel fibers into unconventional layups (cross-ply, quasi-isotropic, and helicoidal patterns) leads to the alleviation of directional dependence of mechanical properties, which is a limitation of the unidirectional samples with fibers.

Launch HN: Hedgehog – Trade Crypto on 130 Exchanges
Hey HN! I’m Colton, a founder at Hedgehog. We make it easy to trade cryptocurrency on any exchange, track all your wallets, and learn about every coin.

As early team members at Acorns, we helped build out the broker-dealer and RIA, but crypto has been a brand new challenge.

We originally got started in crypto while we were running a small consultancy, when three of our clients broke their contracts in the same month: one went bankrupt, one got sued by an ex-partner, and one was out of state--and decided he didn't have to pay us.

That's when we learned about smart contracts and got excited about the idea of automated escrow. Volatility aside, if the technology had been widespread it would have saved us $30k and a lot of grief.

But frankly, getting into crypto is a pain. Finance is complicated enough when dealing with simple equities, but add in secret keys and exchange hacks and you quickly find yourself in chaos. Despite this, 55% of crypto owners report that crypto was their very first investment, ever.

Even as a pro, managing a portfolio of currencies is torturous. Our average client has at least 3 exchange accounts and manages more than 10 different wallets. And the most common tool they all use to track it is Excel--ouch.

That's exactly why we built Hedgehog.

If you don't feel confident in crypto, our Learn content and Discover page are there to help get you up to speed, and we also include loads of research on hundreds of tokens and their teams, with unique wikis for all 1800+ actively traded tokens.

We're already helping individuals and investment firms manage $2.8 million in cryptocurrency, and we've processed $45k in trades since opening up trading to the public around Christmas.

I'm incredibly proud of the team, and I'm excited to hear your thoughts. We're dying to ship features you want. Happy to answer any questions and take feedback here!

-Colton, Taylor, and Jason
That's really cool. It would be interesting to see what that 32% savings adds up to both for typical market bandwidth and AWS like egress rates.

Curious, did your comparison ensure that none of the images lost any detail, etc? Or how much "lossiness" did you introduce to get the 32%?
Not if you plan on using Google search. They discourage such 'behaviour' by throwing captchas at you after a set amount of time.
A sack in this case would be different because in the end it was still controlled by Christiandom, as opposed to the Fall when it switched to being controlled by the Ottomans. I think these small details do matter in this case, but maybe its just me.

I haven't. I think people are too afraid to say "I don't know".

But man, our universe sure is weird. On a fundamental level. I think people under-model just how strange our universe is. Even things like Pi. Why does Pi equal Pi? What an unlikely number to define something fundamental about the universe itself. Or take the logistic map [0]. I mean, what? Why is our universe this way? Or Euler's Identity (e^(pi*i) = -1). Why e? Why pi? I get that the math works, why does the universe need those values for the math to work?

Interesting. I would think though that the move to their own DNS servers could extend to their own ads as well — that is, cutting out the middle man that is Google/etc.

I'm all for news sites, for example, hoisting ads if I knew they were getting the money from those ads, knew the ads were actually coming from their site.
People shouldn't think that this change on its own means they can't be tracked any more, but also this change is worth celebrating -- not all sites use fingerprinting (yet).

But yeah, we still have a ways to go. Small steps.
In theory, yes, in reality, no. The strongest, biggest signal of what ads people will click is what kind of ads they clicked in the past. Content based ads have really bad performance comparably.
NoT really blocking JavaScript / CSS, not preloading and stupidly large images.

BTW I do this for a living for some big brands just dropped FCP from 2.6 to 2.4 and CLS .478 to 0.385 with some tweaks to the preload.
It's inevitable that bigEnergy will dominate any EV charging infrastructure and pricing. Governments collect huge taxes from fuel for travel, some of which they use to maintain roads.

Going from a 3 minute fill up of gasoline or diesel to a 20 minute minimum recharge and having to go to a shopping mall is a currently regressive and inconvenient step. Hopefully as battery and grid tech improves this will become less inconvenient.
Use your browser settings to block third-party cookies altogether. And, better yet, install uBlock Origin and never see an ad again.
Pi-Hole is a DNS solution so it's just blocking DNS lookups. Mine is currently blocking 43.9% of all DNS requests.

Looking at the list of the most deadly non-tropical infectious diseases [1], most can be vaccinated against and/or cured. The standouts remain lower respiratory infections, e.g. influenza, and HIV/AIDS.

When confronted with a novel coronavirus, it took a few months for the world's medical systems to devise various treatments and a vaccine. Neither of those are recurring revenue streams.

Most damning to this conspiracy theory is the recent Hep C cure. That's a real disease. It was profitable to treat. But it's more profitable to cure. Those incentives remain elsewhere. A cure for HIV is worth billions.

Dealing with mortality and sickness is difficult. It's more comforting to some to imagine an evil cabal holding back medicine, and I don't need to take that from them. But if you're entertaining these thoughts as anything more than a coping mechanism, the last half century--or even decade--of progress in curing, not treating, curing a variety of medical issues has been under-reported (lots of niche illnesses) and breathtaking.

That sounds like a legitimate interest to me.
And then just one query comes along where you need to make an update that should be globally visible, and not just visible to the shard.

I can see why you would stick with full Postgres for as long as practicable.
It's a percent of DNS requests. It might be quite difficult to see what percentage of bytes it translate to, since HTTP requests aren't actually sent.

My pihole is showing 18.7%-23% of requests blocked :)
Bad software development slows the web down

This is an empty statement and another overly simplistic answer. Of course bad software development slows the web down, because you're defining slow web sites as being badly developed.
So to you there is no difference working for McDonalds or Canonical or Oracle? And what is your solution? Work for the government? Everyone should work on the family farm because families always treat their members better than anyone else and nobody gets exploited? Do not work at all?

Again, this is like saying that if you push a person hard enough they will commit violence which immediately implies that all people are violent criminals. It’s simply not how that works, and equating all current and past behavior to what someone is capable of is silly.
Poe’s Law was named in 2005. Which was interesting news to all of us on Usenet for whom this phenomenon was already known before Eternal September or Green Cards stole the show.

Sarcasm was already dead before “spam” meant ads instead of scrolling a forum or chat window by repeating yourself (exactly like the Monty Python sketch it alluded to).
It's 2021. Who isn't using an ad blocker?

It feels like he died a decade ago, really drives home just how much of a trainwreck the last year was and how utterly exhausted by most things I feel.
If you wanted to do this, it's probably a lot easier to intercept the RF to the ground stations.
The shocking part isn't so much the murder as it is the brazenness, i.e., ineptitude of the whole thing. The Saudis seemed to act like it was their right to kill Khashoggi, else they would have planned better to avoid getting caught.

This is even more evident in reactions to the Russian governments assassinations, attempted and successful. It's not that we don't think they'd try to kill people, but the way they don't really even bother to cover it up is what is really shocking. It's a slap in the face of the idea of law and order - murderers are at least supposed to do their best to hide their actions.

What do you think the availability of LTO 6 drives will be in 10 years? The major benefit of SATA, and even Bluray, is the interface and drive will likely still exist in 10 years.
Of those I only go to github. And for now it still works without javascript execution.

Sites that want or have to serve everyone do not use the web as an application because they know it doesn't work. Gov.uk and amazon.com for example went out of their way to work for all people of the world. And Gov.uk has found approximately 1 in 96 actual people do not have JS turned on[1].

For fancy businesses with other businesses as their end users you can get away with not supporting everyone. It doesn't effect their income so it doesn't matter. But the reality is that JS-application sites fail 1% of users and for actually serving everyone that 1% matters.

Absolutely. Last night I had the misfortune of experiencing a comcast outage. Although I live in the city, my neighborhood has horrible cellular coverage. Comcast serves their outage data through their account management portal which happens to be a massive, bloated, slow javascript app. It took minutes to load on my phone to find out if there was an outage.

All of this for something that should be no more complicated than entering a zip code and getting back a small page with information about whether or not there is an outage.
Neither does biometric data?

How can I tell minority status from a fingerprint or retinal scan?

It seems rather arbitrary to treat name and address differently from fingerprints.

I would argue that minority status correlates more heavily with name than with retinal patterns.
Not if you’re on a smartphone. This is one of the problems with mobile — no way to have one app interact with another. Many people with disabilities rely on this sort of functionality on desktop and cannot use it on mobile. The only accessibility features that exist are the ones the OS implements.
Its more the CopyPasta of god knows how many JavaScript frameworks.
That is what I currently do. It turns casual browsing into a frustrating scavenger hunt. The whole point of the web was to make links effortless so you could browse sites. This breaks that whole model.
Basically their version of AdSense. Integrate Amazon shopping ads into your content.
Negative post here - interesting research but shame on reuters / researcher for pretending this is biomimicry. The article does not say at all how the concrete has anything to do with lobster shells.

Further, rotating layers to change the bulk performance of materials composed of anisotropic plies is very old technology developed originally for aerospace / racing applications.

Ansys has an entire package devoted to the analysis of structures made from anisotropic materials in this way.

> First of all, all of these things can be turned off;

They cannot. Reporting off, telemetry off, automatic updates off, every related setting in about:config off -- Firefox still transacts data with not one but several Mozilla domains upon launching.

Mozilla can't ethically constantly talk about privacy out of one side of its mouth while collecting data that can be used to track users who have explicitly requested them not to do that out of the other side.
Or perhaps as time passes, a greater portion of their storage is rarely accessed archives so more disks in % are sitting doing nothing.
GitHub fits the document model pretty well in my opinion.
Yes! Thank you for this (in hindsight, obvious) idea.

> companies [don’t] stop spying just becouse you paid them

I think Windows (10 especially) is Exhibit A here (its “users” are definitely the product, but MS is happy to take their free money — or not, you can download it for $0 from their site, and cheap activation keys are easy to find), and the world’s first trillion dollar company is Exhibit B — its end-users are customers in many senses of the word, and they’re not the product, but a product that they offer to their walled garden’s developers with strings attached.
My first real job 5 years was remote for a US company working from home from Montreal. I made about 120k USD which is pretty high for Montreal.

I am still working remotely, but for a multinational with offices in Canada. I manage to keep my US-like compensation by pointing out that with remote work there is very little frontiers and that the market is now global. This was pre-covid.

I imagine this new reality will drive pay down in the US and up in Canada.

No, that's not the reason, given that PrEP exists. The actual reason is that Truvada, like other healthcare, can be hard to get in the American system.
COVID takes a few days to show symptoms and get diagnosed. HIV takes a lot longer.

> In their monthly Vital Signs report out Tuesday, the Centers for Disease Control and Prevention reported that the median time between infection and diagnosis with HIV was three years in 2014, about seven months shorter than in 2011.

If you got HIV in 2020, chances are you don't know about it yet.
You classifying 11 writes per second as "heavy use" reminds me of how people on average completely underestimate how fast computers actually are (when they're not bogged down by crappy programs).
> It's not conspiracy thinking to look at the incentive structures within systems to predict possible negative outcomes

It is when one mischaracterizes the system.

Medical research is not an oligopoly. It is oligopolistic within some domains, but as we've seen with the Covid vaccine, there are at least four nation-state domains (e.g. Russia, China, India and "the West") operating competitively, and within those domains, there are varying degrees of competitiveness (e.g. Pfizer vs. Moderna vs. AstraZeneca).

If you have a cure to something everyone else can only treat, you'll make a money selling the cure and taking your competitors' market share. Because if you don't, they will. It's a classic cartel / prisoner's dilemma problem with the added explosive of a multi-decade patent-protected monopoly for the first mover.
Good point, bad analogy. Twitter treats pedophiles really well.
Because cryptocurrency is a scam.
AWS, Google, Robin Hood all having connection problems
No, this is like whining that plastic straws are bad for environment. Yes they are, they kill animals in the wild but stray/old nets are far bigger problem for sea turtles.

Is it worth investigating a stolen candy bar? Maybe going after organized crime is more worthwhile.

Both are tangential issues that we shouldn't be talking right now as we have far bigger problems to deal with. That doesn't mean its a free pass, just that priorities should be not hijacked by publicity etc
It’s the best of both worlds. I can selectively move things off and seamlessly have them move back.

Yev from Backblaze here -> We just started deploying more of them! We added almost 6k WDC drives in Q4 - so we're getting more of them in the fleet! They have a pretty low AFR - but haven't been deployed for too long, so they'll be interesting to follow!
Which “them”?
Right. A person is good and moral until they are starving. Then thing change a lot. The person may steal, rob, even murder. Therefore all people are murderers and we should get rid of them. QED.

I am not saying businesses should have a carte blanche to do what they want. Far from it. But in the sense that some corporations tend to behave better than others, just like some individual people tend to behave better than others, we should recognize that it is better to push all to behave better than to get rid of all of them on the grounds that the worst ones are beyond redemption.
Sorry, I didn't mean their _own_ servers, I just meant hard-coding 8.8.8.8 into the DNS settings, for example.

I wonder if you could hijack those requests at your router and send them back to your Pi-Hole? But then they just switch to DNS over TLS...
jQuery isn't the problem as much as jQuery "needing" to exist is the problem.

Developers still have to make webpages that work with customers that are stuck on old phones which will never see another firmware update, corporate desktops that have some forsaken frozen copy of IE6 that gets used for some legacy corporate platform (and then end users either don't or actually aren't allowed by IT/security to use any other browser), people with PCs that 'still work' (and if you're lucky have Windows XP with whatever it came with)... etc.

Generally we can't have nice things because that legacy cruft is going to be around until all of that legacy falls over and dies so hard that even laypeople consider it laughable to assume it still works. It's got to be like those old blenders or fans... wait they still work; we're cursed forever.

Want the Internet to be fast? jQuery is a defacto standard that needs to be made native in browsers and then when called for not loaded as script but already existing as native code and management models.
And the one that doesn't require JS in that list.

Bad example, I give you that.
He, of course it is. Though, Google etc are doing a good job progressively taking control over email, they already have made running a private mail server a huge pita.
I think you’re overestimating the impact of this. Most web site content these days are served from the web site owner’s own domain.

It’s only if a.com and b.com have (for example) the exact same image URL (c.com/img123.jpg) embedded, and you visit both sites, that this cache partitioning will make a difference.

In essence, there’s very little legitimate Internet traffic that would be effected by this change, but lots and lots of creepy spyware behaviour will be prevented.
That's the first time I hear of Twitter as a platform inherently efficient against misinformation. If anything, it seems uniquely primed to spread it and reward users for doing so.
I don't think my experience is vastly different from yours. I do get some sites where pop-overs or cookie notifications are blocked but it's not clear and you just can't scroll. I could turn off those blocker settings, but the notifications are annoying enough it's worth it.
That's fine for many applications, but for someone like me who has a Continuous Glucose Monitor having my phone/watch be with me at all times is a fact of life. I look forward to the day when my CGM interfaces directly with my watch so I don't have to carry the phone all the time.
Brave doesn't have the features offered by those extensions, it doesn't have anything equivalent to multi account containers, it doesn't have DNS emulation (unless you install Decentraleyes) and it doesn't auto delete cookies (you still need to install Cookie Autodelete). The built in ad blocker is not as advanced as uBlock Origin and that's why I installed the latter as an extension (I turned off the built in one). Anyway IMHO the biggest limitation currently is the lack of containers, because it needs to be built into the browser, there is no 3rd party extension that can give you that.

Remember that the only reason a laser works for this kind of link is that it is very highly collimated. The light scattering from the receiving satellite is diffuse so the intensity will go down very quickly with distance. It might be observable with a suitably large telescope, but I doubt it would be practical.
